WILLIAM SHEPPARD WALLACE or CHARL'OTTE;A 'NORTH cARoLrNA `TABLErmelPRESS Application 'filed May '23,

The object of my inventionis to `provide a novel and more eficientvtabletingpressV for the'use of printing oiiices in holding papertogether until it can :be glued in pads,'and then holding the pads`under pressure While the glue is appli-ed and during the periodrequired for the glue to dry.

It is an especial object of lmy invention to provide a device which willpermit of gluing k a rlarge 'quantity of sheets at onetime andVwliicliwill maintain an even pressure on all parts of the pads. f

It is also an object of my invention to., provide a novel type ofspring,especially designed` for use as a part of myv tableting press.: It isalso an 'objectof my invention tov provide a'device which is adjustablefor use with dilferent sizesheets; and to provide the novel combinationand arrangement of parts disclosed in the 4accompanying drawings, anddescribed in the following specification.

I attainthese and other objects of my invention by the device. shown inthe accompanying illustrations, in which,-v

Figure 1 is a side elevation of my inven tion in use; t n Fig. 2 is afront plan view of same;

Fig. 3 is a perspective'view of the spaced pressure blocks;V

Fig. 5 is a detail-ed view of one of the springs, portions of which arediagrammatr cally shown;

Fig. 6 is a perspective view of diiferent size pads whichcan beheld andglued con. i veniently in my device; l

Fig. 7 is a si-de elevation of a modied and A preferred form of myinvention; Fig. 8 is a face view of the bar 29with the spring section151 attached; and

. Fig. 9 isa side elevation of same.,

. trough 7 which trough is kprovided with Like characters of referencedesignate like 192e.A serial No; 365,551;

suitable sidefstrips v8 to guide the pads of paper n thelower end. ofthetrough 7 isa rigid end strip 9, disposed at right angles to member 7'. ll

Iprovide a pair of blocks, one of which is designate-d llfand the other12,' tohold the pads in'placeon the trough. ,Each of the blocks' 11 and12. is provided vwith ak plurality.V of 'openings 22 and 24, arranged asshown inFigs. 3 andv 4 ofthe drawings. fl also pro'- vide y threevparallel grooves v19in; the outer surfaceof each of thel blocks 11.andr12, in whic'hgrooves. are mountedrthe hooks 2Q, 2.5, and 26.011 oneoftheblocks; and the hooks' 21, 27 and 28 on the otherV block. Hooks 2Oand-21 project over the ends jof the blocks; hooks 25 and27,project'i'nto the openings 22; and hooks 26 and 28 project into theopenings 24, vas shown in Fig. 3. i.

provi-de a` novel type of'spring comprising the spiral sections 15, 16.and 17, with loops l8intervening between these sections and disposedatVsubstantially right angles to the plane of thespirals inthe sections;the

springs also having similar loops 18 at their ends. Any one of the loops18 may be'liooked inthe hooks 2O and 21. s

, ,I provide a'suitable `hinge 6, ,having one of its arms affixed to thetrough 7, and having the other arm a'ixed to the base 5,; the hingelbeing disposed in proximity to the triangular bracket 10. i y

lIn operation the trough may be disposed vin the position shown in Fig.1, resting against the triangular bracket 10, whileV the sheets arebeing stacked on thev trough. .When the sheets to make up the ypads havebeen assembled, and the springsadjusted and fastened toithe respectiveblocksV 11V and 12, to place the.lsheets under pressure, ,the trough isturned to an upright position, thereby giv- Y ing the operator easyaccess lto the stack andY enabling him to remove samefwith littletrouble after the glue has been applied'an'd allowed to dry, so as toplace other stacks in f the trough.

between the sections of the springs `permit of hooking the springs forany desired-length to the respective end blocks 11 and l2, thusproviding a convenientmethod of adjusting the springs to exert therequired pressure on the paper to be glued. The: blocks ll and 12 arepreferablypressed out of onensheet of metal, with the retaining hooksmade apart of the blocks?,` but they may be separate elements asillustrated in the drawings, i'fprev erred. .e "'f y' y The inside ofthe metal blocks are covered Y with cork or felt to keep them fromdamaging or spoilingthe paper against whichthey are placed.

.Under the oldprocess now inzgeneral use, a printer hasto buy'a'separatelpair of boards foreach size of paper he desiresto pad, while myinvention isadj'ustable so that any width of sheets 'from 1l finches .to3 inches or less, such as .the2;pa'ds., B'andCfshown in lFig. 6, maybeheldqin the device and glued together. i I

I may-provide a modification ofA myy invention in which insteadV of thenovel type of springshownl utilize an ordinary'coil spring l5 inanysuitable manner aiiXed' as at Slfto -a strip-of metal 29;this strip ofmetal 29( hav;-

ing severalspacedfholes 30 init which holes function in a similar mannerand in place of they elements 18ct the coil spring shown in Figs. l and24'.' This construction may be utilized in place of thecoil springsbecause of being cheaper to manufacture. The term, coilfspringsf as-usedin the vfollowing Y v claims shall be construed to include anequivavEL) lent; resilient device comprising'a coil `spring aiiixedkto astrip or" metal'and functioning in j approximately the same manner asthe device illustrated. Y j

What I claim is:

ing a--plurality of loops disposed substantially at right angles to theplanes of the coils` of the springs, whereby any of the loops may beengaged in the hooks of the blocks to adjustably exert Vpressure on padsY `or sheets mounted between therespective blocks, the j blocks alsohaving spaced apertures; and hooks projecting from'nthe Vblocks, and thesaid vhooks being engaged by the aforesaid springs for operating onsheets ofpaper of smaller 'size' than the blocks.V
